Margarets Questions and Possible Answers
answers reflecting discussion on the mailing list
5
Question 1

• Question
• Are there any proposed solutions in this space?
• Answer
• Yes, see drafts cited on agenda and presentations
  in second half hour. 

6
Question 2

• Question
• What is the relationship of this proposed work to
  similar activities in IEEE or other standards
  bodies?
• Answer
• As far as we know, there is no work in IEEE on
  this problem.
• WiMax Forum and 3GPP have some ongoing work on
  mobility management in advanced cellular
  networks for which NETLMM could be a candidate
  solution.
• However, neither WiMax Forum nor 3GPP has
  formally requested IETF to work on this problem.

Question 3

• Question
• How is this related to CAPWAP and/or the L2
  mobility management schemes that CAPWAP is based
  upon? 
• Answer
• CAPWAP runs between a WLAN controller and access
  points.
• Solves problem of control of access points and
  traffic management between access points and
  controller.
• NETLMM runs between access routers and a mobility
  anchor.
• Solves problem of localized mobility within a
  broader domain potentially covering several
  CAPWAP controllers.
• Never sees the access points
• CAPWAP and NETLMM solve two complementary but
  separate problems.
• Most WLAN switch products today also have
  proprietary, non-interoperable L2-specific
  protocols for providing IP mobility (marketing
  speak for localized mobility management).
• NETLMM would be an interoperable, L2-independent
  protocol available should the switch vendors
  choose to implement it.

8
Question 4

• Question
• The charter doesn't mention security requirements
  and/or have any specific deliverables related to
  security. 
• Answer
• The charter says
• Security will be defined for the protocol based
  on standard IETF security protocols, but should
  maintain configuration flexibility for varying
  deployment circumstances.
• Is more needed?

9
Question 5

• Question
• Are there any specific drafts that are expected
  to become WG items?
• Answer
• Yes, they are
• draft-kempf-netlmm-nohost-ps-00.txt problem
  statement
• draft-kempf-netlmm-nohost-req-00.txt
  requirements
• Plan is to update drafts based on list discussion
  and issue WG Last Call as soon as the WG is
  chartered.
